China’s Ministry of Ecology and Environment (MEE) announced a proposal to add four chemical substances to the Inventory of Existing Chemical Substances in China (IECSC). The move follows the successful review of documentation under the country’s chemical management regulations and marks the 14th batch (2nd of 2025) under this supplementation process.
Public Consultation Period Now Open
Stakeholders may submit comments on the proposed additions during the designated feedback window:
📅 Comment Period: August 11–22, 2025 🔗 Submission Portal: MEE Official Website
Input from chemical manufacturers, importers, and users is encouraged to ensure transparency and accuracy in the listing process.
Proposed Substances (14th Batch – 2025, 2nd Round)
|
These substances have passed initial compliance screening and are now under consideration for full inclusion in the IECSC.
What This Means for Businesses?
Until officially listed, the proposed chemicals are still considered New Chemical Substances. This means:
• Use, import, or manufacture is subject to MEE Order No. 12
• Companies must maintain valid registrations (e.g., Regular, Simplified, or New Use Notification)
• Compliance obligations remain in place during the review phase
🕒 Timeline: It generally takes 2–6 months after the proposal phase for substances to be formally listed.
About the IECSC
The Inventory of Existing Chemical Substances in China (IECSC) is the official list of chemicals allowed for commercial use without prior registration. It includes substances introduced before October 15, 2003, as well as those later added through MEE’s review and supplementation process.
Even after listing, companies must verify whether a substance is subject to other control measures, such as:
• Hazardous Chemicals Catalogue
• Restricted Substances Lists
• Precursor Chemicals Regulations
Business Actions to Take
To prepare for the possible listing:
• Monitor MEE updates for final approval and formal listing
• Maintain compliance with all obligations for New Chemical Substances until listing is complete
• Adjust compliance documentation and internal systems for upcoming changes
Why It Matters?
Adding chemicals to the IECSC eases the regulatory burden for future handling but requires careful navigation during the transitional phase. Early planning reduces the risk of non-compliance and helps companies maintain smooth operations in China’s chemical market.
